Abstract

A sheet manufacturing apparatus includes a defibrating unit and a sheet forming unit. The defibrating unit includes a rotating unit and a housing, and is configured to carry out a dry-type defibrating process by rotating the rotating unit. The housing includes a cover portion and a fixing unit attached to the cover portion and spaced apart from the rotating unit in a direction perpendicular to an axial direction of the rotating unit so as to form a gap between the rotating unit and the fixing unit. The sheet forming unit is configured to form a sheet by accumulating defibrated material. The rotating unit includes a rotor having protruding sections on an outer circumference of the rotor, and a feeding blade arranged on a side section of the rotor on a side of an input section for the defibration object and configured to generate a flow of air.
